Shell: 6 oil spills 'sabotage' in Nigeria delta

LAGOS, Nigeria -- Royal Dutch Shell PLC says six recent oil spills in Nigeria's southern delta were a result of "sabotage" on one of their pipelines, and that a seventh spill on a nearby line is showing similar damage.

Shell said Monday that its Nigerian subsidiary saw the repeated damage on its 20½-mile (33-kilometer) Okordia-Rumuekpe trunk line that runs through Bayelsa State in the Niger Delta. The oil firm says the damage appears to have been caused by hacksaws.
